Instructions for Use:
- Power Supply Connection: Connect the supply voltage (VCC) between 2.8V and 5.5V to pin 8, and connect pin 4 to ground (GND).
- Output Handling: The digital output is available on pin 5. Ensure proper pull-up or pull-down resistors are used depending on the application.
- Magnetic Field Orientation: Position the sensor such that the magnetic field lines are perpendicular to the top surface of the package for optimal sensitivity.
- Temperature Considerations: Operate within the specified temperature range (-40°C to +150°C) to ensure reliable performance.
- PCB Layout: Follow standard PCB layout practices for surface mount components to ensure good soldering and electrical connections.
- Handling Precautions: Handle with care to avoid damage to the sensitive internal components. Avoid exposure to excessive mechanical stress or corrosive environments.
